ono 

"Over aNd Out"

This is used to end a conversation usually in a instant messaging situation, possibly may be used in a non-real-time communication method such as E-Mail.

This normally is the last thing one says after "bye", "cya", "pce out", etc. It's a way to stop un-ending exchaning of "Bye"(s) at the end.

Person 1: ok then, i'll see ya on monday !
Person 2: sure, and don't forget the home-work !
Person 1: yea ok bye now
Person 1: ono
Person 2: ok bye cya
Person 2: HEY what page is the homework again ?!
Person 2: HELLO ?!? You there ?!
Person 2: :S

Ono 

Ono is a wahed gangster. He probably has 10 pekis. He is definitly not addicted to fortnite, but he will still clap your cheeks in a 1v1. Ono is also better than you in everything, even though he has down’s syndrome.

Omg just clapped my ass-cheeks in a 1v1.
Why is ono so koel (koel is spelled this way because it’s koeler that way, lord Ono chose that)
